Abstract

This work presents a new approach for topology control (TC) in wireless sensor networks (WSN) devised for indoor scenarios with obstacles and no feedback mechanisms. The technique is supported by two novel metrics, namely Blockage Rate and Useful Area Rate, applicable to environments with well-defined obstacles described by Site Specific Propagation models. Simulation results in some realistic scenarios showed that the technique allows to relate connectivity with transmission power levels and to identify critical transmission power levels. Also, it is shown that the technique is equivalent to an approximated mean value in terms of connectivity aspects.
